Master-2H Mono Balanced Power Amplifiers

The Master-2H is a top class power amplifier, designed without any compromises using the best components available on the market! The analogue amplifier stages of this amplifier are non-feedback and DC coupled without any opamps, all discrete. The power supplies of this amplifier are feeded by 4 transformers, 2 per channel and RCORE for preamp sections. Audio-GD uses a technique that is unique in this price range, and designed using "Diamond Cross output stages". This integrated amplifier is a real balanced ACSS solution and delivers 250W per channel @ 8 Ohm and 500W per channel @ 4 Ohm speakers. No wonder this magic amplifier sounds phenomenal! Neutral, detailed, excellent 3D staging and authority and keeps a speaker totally in control!

Master-2H has extremely high fidelity; its SQ is neutral. It will show how good or bad the recording is!

SUMMARY

Real Balanced ACSS Integrated Power Amp

Applies the round-corner style chassis which has lower syntony or vibration. Between the transformers and signal amps resides a thick metal plate to avoid interference.

Fully balanced design, the gain stages and pre-driver stages working on class A , built by discrete analog stages without any OPA or coupling caps in the signal channels.

The output transistors stages work in high idle current state. The Diamond Cross output stage design avoids "switch distortion" as well as class A amps.

Non- feedback ACSS analogue design

80 output transistors: "the King of transistors MJL4281/4302"

Support 250W X2 (8 Ohm) output, 500W x2 (4 Ohm)

The capacitance of the whole machine reaches as high as 260,000 uF, powered by four R cores transformers (Total 1500W)

Completely separated design, separated power supplies for the right and left channels.

In total 4 groups of high-quality class A parallel PSU's to power gain stages. To achieve a high S/N, the control circuit is powered with separate regulators.
